An optical instrument designed to measure the concentration of dust or particulate matter suspended in the exhaust gas passing through a duct, stack, or flue; typically the exhaust gas from an industrial combustion process or air filtration system.

Online Dust Analyzer uses the innovative Dynamic Detection Principle (DDP) which measures fluctuations in the intensity of a light beam, using a folded beam Transceiver /Reflector arrangement. Increased particulate density in the stack causes the scattered light intensity to increase. When calibrated against reference standards, the intensity of this signal relates directly to the particulate concentration in the stack, and this can be used to display as a reading in mg/m³.

Available for SO2, NOx, CO, CO2, etc.

Electrochemical Based Analyzer

Uniphos Stack Gas Analyzer is an online micro controller based system for measuring concentration of various toxic gases in industrial stacks. The analyzer comes with sample conditioning system incorporating dust filters / scrubbers for zero air generation, etc. With a purge system, the instrument can be programmed to periodically purge the sampling probe at required intervals. An inbuilt pump brings the sample from stack to the analyzer. The analyzer also provides Auto/ Remote calibration facility when connected to standard gas cylinder through a calibrator. Modern integrated circuits incorporated in this product provide all required annunciations and data communication to make the analyzer fail safe and user friendly.

Available for SO2, NOx, CO, O2, Cl2, HCL, NH3, etc.

NDIR Based Analyzer

Uniphos NDIR based CEMS are PLC based rugged and reliable system for measuring concentration of various gases from stacks. Non Dispersive Infra-Red technique is highly specific as it chooses gas specific infrared absorption wave length of the target gas by cutting off all other wave lengths. This technique is cost effective and reliable for measurement of gas concentration in parts per million range.
